After JFK's assassination, Robert Kennedy was elected to the United States Senate from New York, and served from 1965 until his death.

Closely associated in memory, the two brothers were not at all close as children. John was eight years older, and rarely spent time with Robert while growing up.

Robert Kennedy proved a staunch political operative on several of his brother's campaigns.

In 1968, Robert Kennedy ran for president. He had just won the California primary when he was shot shortly after midnight on June 5, 1968 by Sirhan B. Sirhan. He died the next day, on June 6, 1968. Like his brother's 1963 assassination, Kennedy's death has been plagued with questions. These questions have led various third parties to come up with theories and solutions to the crime.
